5-HT2A receptor agonist-3

What it means: Purity is the percentage of the desired compound in the supplied material, as stated by the manufacturer. Here it is 98.53%.

Why it matters:

• It tells you how much of the material is the compound itself, which sets the effective concentration in your assay.
• It varies from lot to lot, so it is the value to check when a re-order behaves differently.

How to interpret here: The stated value applies to the material as supplied. A lot-specific Certificate of Analysis is available on request.

Tip: record the purity of the lot you used in your assay notes so a later lot can be compared like for like.

What it means: CAS Number is the CAS Registry Number, a globally unique identifier for this chemical substance. Here it is 1391499-52-7.

Why it matters:

• It identifies the substance unambiguously across suppliers, catalogues and literature.
• It does not change between lots — if it differs, the substance differs.

How to interpret here: Use it to cross-check identity against literature and against other suppliers before ordering.

Tip: quote the CAS number when searching the literature — compound names vary, the number does not.

What it means: Molecular Weight is the molar mass of the compound in g/mol, used to convert between mass and molar concentration. Here it is 420.34 g/mol.

Why it matters:

• It is what you use to weigh out a target molarity.
• It is fixed by the molecular formula and does not vary between lots.

How to interpret here: Use it together with the pack size to work out how many assays a vial will cover.

Tip: note whether the value is for the free form or the salt before calculating a molarity.

What it means: Form is the physical state of the material as supplied. Here it is Solid.

Why it matters:

• It tells you what arrives in the vial and how to handle it on receipt.
• It determines whether you can weigh the material directly or need to reconstitute it.

How to interpret here: Check it against your dispensing workflow — solids need weighing, pre-made solutions do not.

Tip: check the vial on arrival; report any mismatch with the stated form before use.

What it means: Target lists the molecular target(s) this compound is reported to act on. Here it is Human 5-HT 2A Receptor, Human 5-HT 2C Receptor.

Why it matters:

• It tells you what the compound has been reported to act on, so you can judge fit for your assay.
• Potency differs between the listed targets — check the Biological Activity section for the values.

How to interpret here: Treat the list as reported activity, not as a validated selectivity panel.

Tip: confirm the reported potency at your target of interest before choosing a working concentration.

What it means: Storage is the manufacturer's recommended storage condition and shelf life. Here it is 4°C, protect from light. In solvent: -80°C, 6 months; -20°C, 1 month (protect from light).

Why it matters:

• It sets the storage slot you need to have free before the shipment lands.
• It also gives the shelf life you can expect under that condition.

How to interpret here: Follow the stated condition for the vial as received, and the in-solvent condition once you have made a stock.

Tip: aliquot stock solutions before freezing so you are not thawing the whole batch each time.
